| With the development of computer and network technique, more and more adaptive and intelligent web-based teaching system has been successfully implemented. Online education form which combines with the contemporary advanced technology has gradually been accepted and approved as a new way for people to gain knowledge and improve their own qualities. In the meantime, knowledge organization and knowledge representation of web-based education becomes the focus of attention in related fields. At present, lots of online course still not get rid of traditional textbook knowledge organization form which has not taken advantages of online teaching environment. Hence, this paper takes the curriculum of computer organization as an example to illustrate the ontology-based course content organization, and then applies this ontology knowledge model to Moodle, which is an open source e-learning platform.The main works of this paper are as follows:Firstly, this paper summarizes the theoretical basis of education, psychology, computer science for modeling course knowledge ontology, mainly related to cognitive learning, learning science, knowledge representation, ontology and other related theories.Secondly, according to the principles and methods of building knowledge ontology, this paper studies the construction method and the concrete realization of actual course ontology, and then provides the methods and process of the ontology construction for the curriculum of computer organization.Thirdly, this paper studies the persistent storage and analyzing of ontology knowledge model. The Jena component provided by HP lab will be used to persist and parse the ontology model, so that it can be invoked by Moodle.Finally, this paper researches the development methodology of knowledge search and personalized recommendation module based on ontology knowledge mode in the Moodle platform, describing the specific realization of this intelligent search module. |
